Mid 1970’s postcard view of the salt mine at Goderich Ont. The  boats tied up in the background are out of service grain storage boats for the grain elevator. Posted July 7, 24.

Walter E Pfefferle: I see the CP bridge in the top of the picture I guess it was still being used in the '70s.

Dave Hooton: Walter E Pfefferle Used until Dec.1988.

John Vincent commented on Walter's comment
Not a great picture, but a close up of the bridge mentioned in the mid 1970's.

Jeff Pederson: And one in layup.

Robin Gates: Jeff Pederson I loaded the fuel off that boat in the winter before everyone thing laid up and that one’s being decommissioned possibly getting fixed but after it got stuck in the Saint Lawrence they weren’t sure if they were going to fix it or not.

[The laid up freighter is the Tim S. Dool. (paycount of 12) Since it is not a self-unloader, equipment had to be brought in to remove the grain before the reflotation attempt was made. Fortunately, it grounded outside of the channel so it did not stop Seaway traffic for the three weeks that it was grounded. This article said no damage was found. I wonder what needs to be fixed.]
